Abstract |
The potential for the biotreatment of CR(VI) wastes has received increased attention because the microbially mediated processes may offer cods, effective ness and sludge production. There are several biological mechanisms which may be suitable for metal treatments, including trnasofrmation, extracellular bindiing, complex formation, biosorption, and intracellular accumulation. Considering the more immobile and less toxic characteristics of Cr(III), the microbial reduction of Cr(VI) to Cr(III) appears to hold the most promise for the develoment of an innovative biotreatment technology. This reductive biotransofmration nont only leads to Cr(VI) detoxification but precipitates the metal in soils, therefore minimizing its potential risk to human helath and impacted ecosystem through decreases toxicity and exposure. |
